What two numbers have a GCF of 457?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 457.

There is actually an infinite number of answers to this question. First, note that both the numbers we are looking for must be multiples of 457. Below is the beginning list of multiples of 457 (1 through 7) in numerical order.

1. 457
2. 914
3. 1371
4. 1828
5. 2285
6. 2742
7. 3199
etc...

Two numbers that have a GCF of 457 can be 457 and any other number on the list above. Thus, two numbers that have a GCF of 457 are:

457 & 914
457 & 1371
457 & 1828
etc...

That is not all! Any combination of any multiple of 457 and "odd" multiples of 457 will also have GCF of 457. We numbered the multiples above so it would be easy to identify the "odd" multiples (number 1, 3, 5, 7, etc). Thus, here are some more examples of two numbers that also have a GCF of 457.

914 & 1371
914 & 2285
1828 & 2285
1828 & 3199
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 457. The lists we created can go on forever.
